Coined/History
DNA gyrase was discovered and first isolated by Gellert et
al. from E. coli. It has been further studied by this and
other groups and has also been isolated from Micro-
coccus Zuteus.

Definition
Gyrase is the enzyme that unwinds the coiled double-stranded DNA in order to relieve tension for helicase.
